一般情况下,学生刚接触化学时兴趣和求知欲都比较旺盛,这是教师搞好教学的有利条件,但是,在后续学习中,随着化学概念、基础理论的穿插出现,大量抽象概念和化学用语的相继涌入,枯燥乏味的描述性内容接踵而至,学生难以迅速消化、理解、吸收,从而使他们最初的兴趣和求知欲逐渐淡化。因此,如何培养和保护学生的求知欲,使其贯穿于化学教学过程中,是值得我们化学教师重视、研究的问题,根 Under normal circumstances, students are more interested in chemistry and thirst for knowledge, which is favorable conditions for teachers to do well in teaching. However, in the follow-up study, with the advent of chemical concepts and basic theories, a large number of abstract concepts and chemistry Incessant influx of language, boring descriptive content followed, students can not quickly digested, understood, absorbed, so that their initial interest and curiosity gradually diminished. Therefore, how to cultivate and protect the curiosity of students and make them run through the chemistry teaching process is a problem that our chemistry teachers should pay attention to and study.
